IMPROVED BRICK-Darme APPARATUS.-

-tlgt flpbnle maar in in there trtters rttut nur mating @mit nt tige nousV n l TO ALL A.WHOM IT'MAY CONCERN: y

Be it known that LISAAC C. HATCH, of.the city of Camden, county of Camden, and State of ew Jersey, have invented a new and'improved Apparatus for Dryingliricks; and I do hereby-declare that the following is a full, clear, and exact description of the 'construction and operation ofthe same.

My invention consistsof one or more kilns, heated by'steam-pipes Aor hot-air flues, in combination with a `fan'at the rear of each kiln, forcreating a blast within, and discharginf'g` from the kiln the moisture emanating from the drying bricks and taken up by the heated air, all as fully described hereafter.

In'order to enable others skilled in the art to make and use my invention, I will now proceed to describe themanner of carrying the same into effect, reference being had to the accompanying drawing, which forms aV 'part of this specification, and in .whichv Plate 1 represents a. perspective view of my improved brick-drying` kiln, and

Plate 2 a sectional plan of the same. i

The kiln may `consist of a single. long building, of bricks or other suitable material', although I prefer to arrange a series of kilns side by side, as shown in the drawing, cach kiln llaying a roof, perforated at intervals, and having at one or both ends a movable door.l On the bottom of eachkiln, and extending nearly throughout the entire length of the same, is a series of pipes, arranged as shown in plate 2, th'e pipes of one kiln communicating with those of the other, so that steam admitted-at P will first traverse the pipes ofone kiln, then those of the nextkiln, and will finally escape ina condensed form from the pipes of the last kiln of the series, after imparting the desired heat to the interior ofthe Whole ofthe kilns. A

On suitable foundations on the bottom of eachlkiln is laid a railroad-track, communicating with the adjacent brick-fields, and to this track are adapted the wheels of cars, on the perforated platforms of which the newly-moulded bricks are laid, in such a manner thatthe're shall be as many open spaces between them as possible. l Y V l At the rear of each kiln is` a fan, F, attached to a shaft, S, which may be common to the fans ofthe whole of the kilns. i

The kilns having been charged )Vith a number of loaded cars containing bricks fresh from the moulds, the

doors are closedin front, steam is admitted to the pipes P, and the fans'arc set in motion, so as to create ablast of air, which, brought into contact with the pipes, becomes heated, and pervades themassesI of wet bricks on the platforms of the cars, theair in its course taking:r up thel moisture which emana-tes from thc bricks, and passing olif throughV the perforations'in the `roof or sidesgof the kiln. l

` If desired, hot air from a furnace maybe introduced into the'kilns through a pipe, P', and hot-air ilues4 built'in'the kiln may be used in pla'cc of the pipes P,although I prefer the latter, as theypermit of the economizing ofthe exhaust-steam of engines, which are frequently used in ,brick-making establishments.

Without claiming broadly the use, for drying bricks, of kilns heated by steam,

I claim as my invention, and desire to secure by Letters Patent-- One or more kilns, built as herein described, and providedwith hot-air or steam-pipes I? P', in combination with fans F Within the rear ond of each kiln, all constructed, arranged, and operating as 'and for the purpose herein set forth.
